Embodiment Construction

[0014] Specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 with figure 2 As shown, the present invention discloses a buffer ZYQ type-wellhead oil increasing device for pumping wells, which includes two oil outlets 3 located on the opposite side of the wellhead oil increasing device for pumping wells, one connected with the oil outlet channel of the oil pump in the oil field Oil inlet 2, a mud-cleaning port 4 located on the opposite side of the oil inlet, the mud-cleaning port 4 is in a closed state when the device is working, and only when the mud-cleaning operation is performed, the mud-cleaning port 4 to open, and a hydraulically controlled one-way valve located at the connection between the oil inlet and the wellhead oil stimulation device of the pumping well.

[0016] When the hollow piston moves upward, the liquid flows into the buffer. Due to the compressibility of the g...

Abstract

The invention discloses a pumping well wellhead oil charging device with a ZYQ buffer. The pumping well wellhead oil charging device comprises two oil outlets, an oil inlet, a mud clearing port and a one-way valve, wherein the two oil outlets are located on the opposite sides of the pumping well wellhead oil charging device, the oil inlet is connected with an oil outlet channel of an oil well pump of an oil field, the mud clearing port is located on the opposite side of the oil inlet, and the one-way valve is located at the joint between the oil inlet and the pumping well wellhead oil charging device. The pumping well wellhead oil charging device has the advantages that the pressure in an oil conveying and pumping pipe body line on the ground is stabilized, and the pressure is kept stable; the effective filling degree and the pumping efficiency of a deep-well pump are improved, so that the oil production quantity is increased; the flow rate of liquid in an oil pumping pipe body is increased, the ability of the liquid to carry oil sand is enhanced, abrasion to a traveling valve and a fixed valve of the deep-well pump by the oil sand is reduced, and the pump inspection cycle of an oil well is prolonged; mechanical abrasion is lowered, the maintenance quantity is reduced, and the use efficiency is improved.

Description

technical field [0001] The invention belongs to an oil field pumping device, in particular to a buffer ZYQ type-a pumping well head oil increasing device. Background technique [0002] In oil field oil recovery, deep well pump is a kind of special equipment in mechanical oil recovery. During the normal production process of the pumping unit, a large part of the oil wells will have different degrees of sand production. The oil sand entering the deep well pump will directly cause the floating valve and fixed valve of the deep well pump to be closed tightly, resulting in a certain amount of leakage. [0003] For example, the invention whose application number is 200320119962.6 discloses an oil well decompression pump, which is an auxiliary device for enhanced oil recovery of a beam pumping unit in an oil field. The structure consists of a frame, a wire rope transmission mechanism, a speed change mechanism, and a gear pump; the wire rope transmission mechanism includes a conne...
